27 DESCRIPTION
28 -----------
29 You can query/set/replace/unset options with this command. The name is
30 actually the section and the key separated by a dot, and the value will be
31 escaped.
33 Multiple lines can be added to an option by using the '--add' option.
34 If you want to update or unset an option which can occur on multiple
35 lines, a POSIX regexp `value_regex` needs to be given. Only the
36 existing values that match the regexp are updated or unset. If
37 you want to handle the lines that do *not* match the regex, just
38 prepend a single exclamation mark in front (see also <<EXAMPLES>>).
40 The type specifier can be either '--int' or '--bool', which will make
41 'git-config' ensure that the variable(s) are of the given type and
42 convert the value to the canonical form (simple decimal number for int,
43 a "true" or "false" string for bool). If no type specifier is passed,
44 no checks or transformations are performed on the value.
46 The file-option can be one of '--system', '--global' or '--file'
47 which specify where the values will be read from or written to.
48 The default is to assume the config file of the current repository,
49 .git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
50 (see <<FILES>>).
52 This command will fail if:
54 . The config file is invalid,
55 . Can not write to the config file,
56 . no section was provided,
57 . the section or key is invalid,
58 . you try to unset an option which does not exist,
59 . you try to unset/set an option for which multiple lines match, or
60 . you use '--global' option without $HOME being properly set.
63 OPTIONS
64 -------
66 --replace-all::
67 Default behavior is to replace at most one line. This replaces
68 all lines matching the key (and optionally the value_regex).
70 --add::
71 Adds a new line to the option without altering any existing
72 values. This is the same as providing '^$' as the value_regex.
74 --get::
75 Get the value for a given key (optionally filtered by a regex
76 matching the value). Returns error code 1 if the key was not
77 found and error code 2 if multiple key values were found.
79 --get-all::
80 Like get, but does not fail if the number of values for the key
81 is not exactly one.
83 --get-regexp::
84 Like --get-all, but interprets the name as a regular expression.
85 Also outputs the key names.
87 --global::
88 For writing options: write to global ~/.gitconfig file rather than
89 the repository .git/config.
90 +
91 For reading options: read only from global ~/.gitconfig rather than
92 from all available files.
93 +
94 See also <<FILES>>.
96 --system::
97 For writing options: write to system-wide $(prefix)/etc/gitconfig
98 rather than the repository .git/config.
99 +
100 For reading options: read only from system-wide $(prefix)/etc/gitconfig
101 rather than from all available files.
102 +
103 See also <<FILES>>.
105 -f config-file::
106 --file config-file::
107 Use the given config file instead of the one specified by GIT_CONFIG.
109 --remove-section::
110 Remove the given section from the configuration file.
112 --rename-section::
113 Rename the given section to a new name.
115 --unset::
116 Remove the line matching the key from config file.
118 --unset-all::
119 Remove all lines matching the key from config file.
121 -l::
122 --list::
123 List all variables set in config file.
125 --bool::
126 'git-config' will ensure that the output is "true" or "false"
128 --int::
129 'git-config' will ensure that the output is a simple
130 decimal number. An optional value suffix of 'k', 'm', or 'g'
131 in the config file will cause the value to be multiplied
132 by 1024, 1048576, or 1073741824 prior to output.
134 --bool-or-int::
135 'git-config' will ensure that the output matches the format of
136 either --bool or --int, as described above.
138 -z::
139 --null::
140 For all options that output values and/or keys, always
141 end values with the null character (instead of a
142 newline). Use newline instead as a delimiter between
143 key and value. This allows for secure parsing of the
144 output without getting confused e.g. by values that
145 contain line breaks.
147 --get-colorbool name [stdout-is-tty]::
149 Find the color setting for `name` (e.g. `color.diff`) and output
150 "true" or "false". `stdout-is-tty` should be either "true" or
151 "false", and is taken into account when configuration says
152 "auto". If `stdout-is-tty` is missing, then checks the standard
153 output of the command itself, and exits with status 0 if color
154 is to be used, or exits with status 1 otherwise.
155 When the color setting for `name` is undefined, the command uses
156 `color.ui` as fallback.
158 --get-color name default::
160 Find the color configured for `name` (e.g. `color.diff.new`) and
161 output it as the ANSI color escape sequence to the standard
162 output. The optional `default` parameter is used instead, if
163 there is no color configured for `name`.
165 -e::
166 --edit::
167 Opens an editor to modify the specified config file; either
168 '--system', '--global', or repository (default).
170 [[FILES]]
171 FILES
172 -----
174 If not set explicitly with '--file', there are three files where
175 'git-config' will search for configuration options:
177 $GIT_DIR/config::
178 Repository specific configuration file. (The filename is
179 of course relative to the repository root, not the working
180 directory.)
182 ~/.gitconfig::
183 User-specific configuration file. Also called "global"
184 configuration file.
186 $(prefix)/etc/gitconfig::
187 System-wide configuration file.
189 If no further options are given, all reading options will read all of these
190 files that are available. If the global or the system-wide configuration
191 file are not available they will be ignored. If the repository configuration
192 file is not available or readable, 'git-config' will exit with a non-zero
193 error code. However, in neither case will an error message be issued.
195 All writing options will per default write to the repository specific
196 configuration file. Note that this also affects options like '--replace-all'
197 and '--unset'. *'git-config' will only ever change one file at a time*.
199 You can override these rules either by command line options or by environment
200 variables. The '--global' and the '--system' options will limit the file used
201 to the global or system-wide file respectively. The GIT_CONFIG environment
202 variable has a similar effect, but you can specify any filename you want.
205 ENVIRONMENT
206 -----------
208 GIT_CONFIG::
209 Take the configuration from the given file instead of .git/config.
210 Using the "--global" option forces this to ~/.gitconfig. Using the
211 "--system" option forces this to $(prefix)/etc/gitconfig.
213 See also <<FILES>>.
216 [[EXAMPLES]]
217 EXAMPLES
218 --------
220 Given a .git/config like this:
222 #
223 # This is the config file, and
224 # a '#' or ';' character indicates
225 # a comment
226 #
228 ; core variables
229 [core]
230 ; Don't trust file modes
231 filemode = false
233 ; Our diff algorithm
234 [diff]
235 external = /usr/local/bin/diff-wrapper
236 renames = true
238 ; Proxy settings
239 [core]
240 gitproxy="proxy-command" for kernel.org
241 gitproxy=default-proxy ; for all the rest
243 you can set the filemode to true with
245 ------------
246 % git config core.filemode true
247 ------------
249 The hypothetical proxy command entries actually have a postfix to discern
250 what URL they apply to. Here is how to change the entry for kernel.org
251 to "ssh".
253 ------------
254 % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'
255 ------------
257 This makes sure that only the key/value pair for kernel.org is replaced.
259 To delete the entry for renames, do
261 ------------
262 % git config --unset diff.renames
263 ------------
265 If you want to delete an entry for a multivar (like core.gitproxy above),
266 you have to provide a regex matching the value of exactly one line.
268 To query the value for a given key, do
270 ------------
271 % git config --get core.filemode
272 ------------
274 or
276 ------------
277 % git config core.filemode
278 ------------
280 or, to query a multivar:
282 ------------
283 % git config --get core.gitproxy "for kernel.org$"
284 ------------
286 If you want to know all the values for a multivar, do:
288 ------------
289 % git config --get-all core.gitproxy
290 ------------
292 If you like to live dangerously, you can replace *all* core.gitproxy by a
293 new one with
295 ------------
296 % git config --replace-all core.gitproxy ssh
297 ------------
299 However, if you really only want to replace the line for the default proxy,
300 i.e. the one without a "for ..." postfix, do something like this:
302 ------------
303 % git config core.gitproxy ssh '! for '
304 ------------
306 To actually match only values with an exclamation mark, you have to
308 ------------
309 % git config section.key value '[!]'
310 ------------
312 To add a new proxy, without altering any of the existing ones, use
314 ------------
315 % git config core.gitproxy '"proxy-command" for example.com'
316 ------------
318 An example to use customized color from the configuration in your
319 script:
321 ------------
322 #!/bin/sh
323 WS=$(git config --get-color color.diff.whitespace "blue reverse")
324 RESET=$(git config --get-color "" "reset")
325 echo "${WS}your whitespace color or blue reverse${RESET}"
